The letter was launched for signing in June by Wellington mayor and LGNZ National Council member Justin Lester, supported by Auckland mayor Phil Goff and Dunedin mayor Dave Cull. The letter calls on the Government to impose a levy on single use plastic bags, or to give individual councils the ability to regulate themselves.
Mr Lester said there is clear public will for a levy on plastic bags.
"Not only are 90 per cent of New Zealand's cities and towns are represented, but what we've seen over the past month is that the majority of New Zealanders support this levy, and most notably, retailers are on board too."
LGNZ president Lawrence Yule says councils and communities take their environmental responsibilities seriously. A levy on plastic bags would act as a deterrent at the point of sale and go some way towards removing these harmful products from the waste stream.
"It's clear to us that we need to do more to minimise the impact of plastic bags on our environment," Mr Yule says. "Plastic bags cause harm in their creation, when they go to landfill and when they are littered."
